Description
Technical field
The utility model relates to the vehicle for construction technical field, relates in particular to a kind of building hoist.
Background technology
The driver train that the building hoist of prior art adopts, the wherein most application of rubber pad of the shock attenuation unit of driver plate and nylon cushion.The problem that this method with rubber cushion exists is, is only applicable to the elevator type of common rising or falling speed, and the service life of rubber pad is partially short, and amount of compression is limited.The available technology adopting polyurethane rubber cushion that also has replaces rubber pad, is that rubber pad or the compression value of this material of polyurethane rubber cushion are generally all used within one millimeter, and shock resistance, to absorb vibration performance poor.
Along with constantly increasing of elevator shipping height, running velocity improves constantly, larger raising and the innovation of performance need of the applied shock attenuation unit in driver plate position of elevator drives mechanism, the elevator driver plate connects in the urgent need to better oscillation damping method design utility model being arranged out with frame.
Available technology adopting adds the practice of spring damping on drive assembly trolley frame and hanger that cage connects.Due to the inapplicable deflection load-bearing stress operating mode of this method, drive trolley frame force status sway, the both sides amount of spring compression differs larger, differs from 2 times of left and right through test.The defect existed is that this can cause the stressed serious overbalance of train, makes the serious variation of running stability.And following two factors have been aggravated this phenomenon: one driver train and cage attachment pegs are that sensor pin is subjected to stress to produce distortion, and two stressed differing of pin are caused too greatly the serious unbalance loading of trolley frame, make load-bearing train fault rate high, and shorten service life; The stress that its two deflection load-bearing stress makes the tooth bar roller be subject to the frame conduction makes roller easily loosening fragile.
The external product of prior art changes into by stress point the trolley frame center that drives, and connects cage with the pull bar with spring, has solved the advantage of application spring damping, the spring damping that made the elevator drives winding machine.But this method is not suitable for China's production system: China's product is lifting driving rack deflection body frame one side, the practice advantage of sway is to economize with material, tooth bar is at body frame center Traction Drive trolley frame (driver train) reasonable stress, but body frame (standard knot) material therefor will strengthen.
The external product band spring pull bar type of prior art, stress point is concentrated at deceleration box top rod stress point stress, and external product is still used the cast steel casing, can not apply aluminium alloy box, due to the cast steel casing from great, be unfavorable for energy-conservation, especially the position portative elevator more outstanding.
The utility model patent (construction) elevator driver plate spring damper.On driver plate, install spring damper additional and just solved this difficult problem.This spring damper makes the shock attenuation unit of domestic elevator product stride into the spring epoch.The complete machine running noises is significantly reduced, and running stability significantly improves.Different type of machines increases load raising speed and all can easily tackle.Driver train can be applied the retarder of aluminium alloy box, and (special-purpose helical gear reducer) aluminium alloy box slows down and thinks highly of 80 kilograms, and only two retarders just cut more than 100 kilogram of deadweight.Equal province and go out a kilowatt of eletctric energy (KWE).The Novel helical gear retarder is higher by 20% than old product worm reducer efficiency.New-type retarder becomes large because the high starting of efficiency stops impacting, and must be furnished with the new vibration reducing measure that adapts and just can bring out the best in each other.
The utility model patent also has a present product of China and foreign products not to possess characteristics: not only driver plate top is equipped with spring damper, and the driver plate bottom also is equipped with this device.Like this, elevator starts the effectiveness in vibration suppression that can obtain in the operational process stopped in rise and fall.
Elevator is impacted and can be absorbed by the lower spring shock attenuation unit to moving deadweight by quiet when descending starting.It is just more important that cage drops on energy disperser the effect of shock attenuation unit at present at bottom.This point does not cause the transmission trolley frame to tilt to rock because external product descends shock attenuation unit.Larger to the complete machine damage.
Summary of the invention
The utility model, in order to solve the prior art above shortcomings, provides a kind of building hoist; The shock resistance of the utility model shock attenuation unit, and to absorb vibration performance good, and the complete machine running noises is low, and running stability is high, can meet different type of machines in large load, high-speed running state, is specially adapted to the elevator that shipping height and running velocity are high.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of building hoist, comprise frame, driver train, driver train is connected with frame by driver plate, driver plate is provided with tooth bar, driver train comprises reductor, retarder is provided with the helical wheel with the tooth bar engagement, described driver plate top is connected with the upper spring shock attenuation unit, described upper spring shock attenuation unit comprises disk spring, the spring inner sleeve, in spring, be arranged with the through hole of axial zone step, in through hole, be provided with attaching parts, described disk spring endoporus coordinates with the cylindrical of spring inner sleeve, disk spring top is provided with the upper gear pad with endoporus, the endoporus of upper gear pad coordinates with the cylindrical of spring inner sleeve, the bottom of disk spring is provided with driver plate header board with holes, the spring inner sleeve is connected by attaching parts with the driver plate header board, the top of described upper gear pad contacts with the top rail beam slab of frame.
